An adult male desert spiny lizard (Sceloporus magister) usually has conspicuous blue/violet patches on the belly and throat, and a green/blue color on its tail and sides. Native to the Chihuahuan Desert and Sonoran Desert of North America, like many desert lizards, desert spiny lizards adjust their internal temperature by changing colour so they are darker during cool times, which allows them to absorb more heat from the sun, and become lighter during warm times so they reflect more solar radiation. The desert spiny lizard also uses camouflage so it is not so easily seen by predators.
